GRP septic tank with biological filter<\/strong> for the biological treatment of wastewater<\/strong> similar to domestic from small and medium communities, achieving good performance thanks to the combination of two processes for the degradation of organic matter: anaerobic and aerobic<\/strong>.<\/p>\n

Operation:<\/strong> it consists of three chambers. The first two settle and digest the organic matter (anaerobic process) and the third houses a biological filter<\/strong> where the aerobic biomass that completes the purification develops.<\/p>\n

Design:<\/strong> made of glass-fibre reinforced polyester (GRP), with PVC connections and threaded inspection covers. A compact, sturdy unit, adaptable to the ground.<\/p>\n

Maintenance:<\/strong> emptying and cleaning must be carried out once a year by an authorised operator (removal of sludge and floating matter from the settler-digester) and pressurised water must be passed through the biological filter; afterwards, fill the unit with clean water.<\/p>\n

Options:<\/strong> level indicator.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
